This has been a chronic issue for several months with countless promises that the technical team is working on a fix. Every few weeks we receive an update with a new promise, the last was:

"The next update regarding the issue 'QBO UK - Customer’s invoice blocked, bounces back or getting rejected when being sent.' has been scheduled for 9/12/2022. Alternatively you will be updated sooner if new information arises, a resolution if found or a fix is deployed in product."

It's now the end of September and there is been no update, no communication, nothing. We will be switching to Sage as soon as possible.
